This method has in fact 6 volumes. 3 volumes per level, there are 2 levels (beginner and already practicing). Each level contains: a book full of exercises in Japanese (kanji have their corresponding written in kana just above), the same volume in romaji (not recommended if you want Verily learn Japanese) and a third on vocabulary and grammar. The exercise books are very well done for each year you have an example that just follow. A booklet solutions is provided in order to check. There are also audio tape to learn to pronounce correctly. The progression of the method is regular but échellonée. And what's nice is that has gradually as you advance in the lesson exervices well use what you've already seen. This helps you remember things for not oubliers. In principle, I do not put the maximum rating, we can always do better. But it's still a very good method that starts from zero (unlike other ...).
